Cantex 5133717 – Frequently Asked Questions
1) What sizes does the Cantex PVCBA3 PVC box adapter come in?
Four trade sizes: 1 inch, 2 inch, 3 inch and 4 inch. Each is a separate part number, so order by size: 5133717 for 1 inch, 5133720 for 2 inch, 5133722 for 3 inch and 5133724 for 4 inch. Construction is the same PVC across all four, so a job spanning several sizes stays on one adapter family.
2) Is the Mulberry 11214 CV52R3 box adapter a substitute for the Cantex 5133711 PVCBA3?
No. The Mulberry 11214 is a CV52R3 4 inch square-to-3 inch round box adapter, so it converts one box opening shape to another. The Cantex 5133711 PVCBA3 is a PVC adapter made to connect a standard electrical box to a Cantex enclosure, and it is offered in 1 inch, 2 inch, 3 inch and 4 inch sizes. If the job calls for a square-to-round box conversion rather than a box-to-enclosure transition, the two are not interchangeable.
3) What does a PVC box adapter actually do on a non-metallic conduit run?
It makes the transition between a standard electrical box and a Cantex enclosure in a non-metallic system. Instead of fabricating a connection or dropping in a metallic fitting, the PVCBA3 gives you a purpose-made PVC interface at the box-to-enclosure joint. Sized 1 inch through 4 inch to match the configuration in front of you.
4) Is a PVC adapter the right choice, or should I use a metallic one?
Use the PVC version where the rest of the system is non-metallic. The PVCBA3 is PVC throughout, which keeps the joint corrosion resistant and non-conductive and keeps the assembly consistent with PVC conduit and enclosures. If your boxes and raceway are metallic and bonded as part of the equipment grounding path, a non-metallic adapter is the wrong part for that connection.
5) Which box adapter should I use for a non-metallic PVC system where a non-conductive fitting is required?
The Cantex 5133711 PVCBA3 is built from PVC and is intended for non-metallic conduit and enclosure systems where a lightweight, non-conductive, corrosion-resistant adapter is preferred over metallic alternatives. The comparable Mulberry 11214 CV52R3 is a 4 inch square-to-3 inch round box adapter and serves a shape-conversion role rather than a PVC enclosure transition.
6) I need box adapters in bulk for a large job - how do the Cantex PVCBA3 and Mulberry CV52R3 differ in how they are supplied?
The Mulberry 11214 CV52R3 is supplied as a pack of 100 of a single configuration, a 4 inch square-to-3 inch round adapter. The Cantex 5133711 PVCBA3 is ordered by size, with 1 inch (MPN 5133717), 2 inch (5133720), 3 inch (5133722) and 4 inch (5133724) available, so a multi-size job can be covered from one PVC adapter family with the same construction and connection approach in every size.
7) Can I use the Cantex PVCBA3 in commercial and industrial work, or is it residential only?
All three. The adapter is intended for residential panel and box connections, commercial and industrial electrical installations, and both new construction and renovation. Multi-size box-to-enclosure transitions on larger sites are a named application, which is why the range runs to 4 inch.
8) Do all four sizes of the PVCBA3 connect the same way?
Yes. Every size in the PVCBA3 series shares the same PVC construction and the same connection approach, so spec selection on a multi-size project comes down to picking the trade size, 1 inch through 4 inch, and nothing else changes.
